  • 1987 2.5 HP Water Pump

    I recently purchased this 2.5 Hp and it runs great but does not appear to be cooling. I purchased a new water pump kit but can not get the shaft to come out of the ngine so I can ***emble the water pump around it. Is this situation normal. I can not insert the spine in the pump without getting the shaft out. Someone please help.

      The engine gas no neutral

      That is what I thought. I don't think it has a neutral so it is always in gear. Do you think i should pull on it with some vice grips?

          Drive shaft will not come out!

          I used a cloth and vice grips and hit it with a hammer an still can't get it out. Is it possible to get at it from the power head? this is getting frustrating.

            PB Blaster

            Will it hurt anything if I spray PB Blaster toward the powerhead? It does not make sense that the shafts turns freeing but will not drop out.

                Still will not ocme out

                Is there a clamp or something holding it in? I just doesn't make sense that it turns so freely but won't come out.

                  No there is no clamp holding in place. There is an oring, but that is just a seal to help keep dirt out.

                    Finally Got It

                    We removed the whole exhaust housing up to the engine. Took off the retaining cap and sprayed it with PB Blaster and let it set a few hours. We put the retaining cap back on and used a hammer with vice grips to knock it out. just need to file off vice grip marks and re***emble.

                      2.5 running again

                      After finally changing the water pump I got the engine running again but I have no sighs of any water cooling the engine. Were is the water suppose to exit the engine?

                        Water is now spiting out about half way down the shaft. does that seem correct?

                          Yes many models will shoot water out the midsection.
